Abstract The re-exploration of the extranuclear electron movement needs to understand the essential law of the extranuclear electron movement from the perspective of disciplinary understanding in the selective compulsory stage of high school.Through the evolution process of atomic structure model, the original question of electron movement outside nuclear is extracted, and the students are guided to construct atomic structure model developmentally in the learning task of primitivism problem solving. Based on the nature of the motion of microscopic particles, the motion characteristics and description of the extranuclear electrons are understood, and the microscopic perspective of the motion of the extranuclear electrons is constructed.
